Tacrolimus-Induced Rosacea-Like Dermatitis: A Clinical Analysis of 16 Cases Associated with Tacrolimus Ointment Application

Background: Recently, reports have indicated that the continuous use of topical calcineurin inhibitors such as tacrolimus may induce rosacea-like dermatitis (RD). Objective and Methods: To assess clinical features of RD associated with tacrolimus, 44 cases of patients diagnosed with RD between 2005 and 2010 at our hospital were retrospectively reviewed. Results: In total, 22 cases were caused by topical steroid use, 8 by topical tacrolimus use, and 8 by consecutive treatment with topical steroids and tacrolinnus. Clinical presentation was basically similar among the 3 groups, although the nose was less frequently affected and pustules were rarely observed in the latter 2 sets of cases. Demodex mites were often found in smears of skin lesions from patients with RD caused by steroids and tacrolimus. Treatment with topical metronidazole was effective in most RD patients. Conclusion: Topical tacrolimus is becoming an important cause of RD along with topical steroids. Copyright (C) 2012 S. Karger AG, Basel
